Judo
is mainly a sport in which two competitors try to throw each other using
different techniques to obtain maximum points, therefore winning the bout.

A
contest can also be won by means of a hold-down, this is where the competitor
after throwing his opponent holds them down on their back for a period
of up-to 20 seconds.
Or
By submission of your opponent when armlocks or strangles are applied
(over 14 years only).

Judo
is also used in self-defence, all the techniques that are taught can be
used to defend yourself against attackers, examples of these are shown
periodically at lessons.
